| Research Abstract |
Energetic charged particles trapped in Earth's magnetosphere are known to be drastically changed during magnetic storms, but overall mechanisms leading to the change remain unsolved. We developed the comprehensive simulation code that deals with the magnetospheric system from a unified point of view. Major results include a rapid reconstruction of the outer radiation belt due to force imbalance in the inner magnetosphere, rapid transport of electromagnetic energy from the inner magnetosphere to the equatorial region on the ground.
